docker-engine 1.12.4
一、安装 docker-engine 1.12.4
1、先检查是否安装旧版本docker
rpm -qa|grep docker 如果有先卸载 yum remove docker*
2.编辑docker.repo文件,写入如下内容
cat >> /etc/yum.repos.d/docker-main.repo << EOF name=Docker main Repository baseurl=https://yum.dockerproject.org/repo/main/centos/7 enabled=1 gpgcheck=1 gpgkey= EOF
3.安装docker
yum -y install docker-engine
4.关闭防火墙和selinux
systemctl stop firewalld.service systemctl disable firewalld.service 关闭selinux sed -i ‘s/SELINUX=.*/SELINUX=disabled/g‘ /etc/selinux/config 重启
5.增加tcp监听端口
修改/lib/systemd/system/docker.service sed -i ‘s/ExecStart=.*/ExecStart=\/usr\/bin\/dockerd -H unix\:\/\/\/var\/run\/docker.sock -D -H tcp\:\/\/0.0.0.0\:2375/g‘ /lib/systemd/system/docker.service
6.重启docker
systemctl enable docker.service systemctl restart docker ps -ef|grep docker 能看到docker启动及2375端口
7、安装pip及docker api
yum -y install epel-release yum -y install python-pip pip install docker-py docker-compose
二、配置consul cluster
1、创建 consul 用户及组
groupadd -g 1000 consul useradd -u 100 -g 1000 -s /sbin/nologin consul
2、创建consul 数据存储文件夹
mkdir -p /opt/consul/{data,conf} chown -R consul: /opt/consul
3、拉取consul镜像
docker pull progrium/consul 提示:目录没有官方出consul镜像,以上consul镜像是星数最高的,也是consul官方推荐的第三方docker image
4、启动consul server 192.168.1.66
docker run -d -p 8300:8300 -p 8301:8301 -p 8301:8301/udp -p 8302:8302 -p 8302:8302/udp -p 8400:8400 -p 8500:8500 -p 8600:53 -p 8600:53/udp -v /opt/consul/data:/data -h consul-s1 --restart=always --name=consul-s1 progrium/consul -server -bootstrap-expect=1 -ui-dir=/ui -client 0.0.0.0 -advertise 192.168.1.66

8、配置consul-template nginx启动脚本 /etc/init.d/nginx_ctmpl
#!/bin/bash # chkconfig: 2345 10 90 # description: Start and Stop redis PATH=/usr/local/bin:/sbin:/usr/bin:/bin EXEC=/usr/bin/consul-template CONF="/opt/consul/conf/nginx_ctmpl.json" case "$1" in start) PID=$(ps -ef | grep -v grep | grep "$EXEC -config $CONF" | awk ‘{print $2}‘) if [ -n "$PID" ] then echo "haproxy_ctmpl is running..." else echo "Starting haproxy_ctmpl server..." $EXEC -config $CONF > /tmp/nginx_ctmpl.out 2>&1 & fi ;; stop) PID=$(ps -ef | grep -v grep | grep "$EXEC -config $CONF" | awk ‘{print $2}‘) if [ -n "$PID" ] then echo "Stopping..." kill -9 $PID sleep 2 else echo "haproxy_ctmpl exists, process is not running." fi ;; restart|force-reload) ${0} stop ${0} start ;; *) echo "Usage: /etc/init.d/tmpl {start|stop|restart|force-reload}" >&2 exit 1 esac
9、设置开机启动
chmod +x nginx_ctmpl chkconfig nginx_ctmpl on service nginx_ctmpl start
七、测试是否自动发现
docker run -ti -d -p :80 eboraas/apache-php docker run -d -ti -p :80 nginx
1、打开 http://192.168.1.66:8500/ui/#/dc1/services
2、http://192.168.1.23:8080/#/containers
查看shipyard 管理平台
账号admin密码 shipyard
3、haproxy
http://192.168.1.70:8888/admin?stats
http://192.168.1.71:8888/admin?stats
账号:admin 密码admin
最后:注意事项:consul registrator 是基于端口发现的不映射端口是发现不了的
consul 服务挂了整个宿主机运行应用将不可见。registrator 是基于镜像名加端口服务
镜像名称为nginx 映射端口80 对外发现的服务名称nginx-80
像集群添加宿主机
consul registrator swarm-agent registrator 链接consul 端口请使用宿主机的consul 端口
使用其它机器端口如果其它机器挂了这台宿主机的应用不可被发现
